Abstract: A cover assembly for the box of a pick-up truck. The cover assembly has a rigid cover that is sized to fit between the side walls of the box when in the closed position closing the open top of the box. The assembly includes support ledges fastened to the inside of the side walls of the box for supporting the cover in the closed position. The support ledges carry female pivots spaced from the side walls to form gaps. The cover carries male pivots that enter the gaps in the closed position of the cover, the male pivots in a non-cooperating position with the female pivots. When the cover is lifted from either side of the box, the male pivot on the opposite of the box moves to cooperate with the female pivot on that side to form a longitudinal pivot about which the cover swings when opened.

Abstract: An   instrument  for performing highly  accurate  PCR employing a sample block in microtiter tray format.   The sample block has local balance and local symmetry.  A three zone film heater controlled by a computer and ramp cooling solenoid valves also controlled by the computer for gating coolant  flow  through  the  block  controls  the  block temperature.    Constant bias  cooling is  used  for  small changes.    Sample  temperature  is  calculated  instead  of measured.  A heated cover deforms plastic caps to apply a minimum acceptable threshold force for seating the tubes and thermally isolates them.   The control software includes diagnostics.   An install program tests and characterizes the instrument.  A new user interface is used.  Disposable, multipiece  plastic  microtiter trays  to  give  individual freedom to sample tubes are taught.

Abstract: A fan for moving air into or out of a building comprises a novel centrifugal mechanism for operating an associated shutter made of a plurality of pivoted vanes and a central vane interconnected by two heavy tie rods, a wall-housing defining a quasi square air flow passage having large radii at each corner, an electric reversible motor and an impeller which are fastened to a central structural member. The centrifugal mechanism is made up of a smaller number of parts and joints required to prevent looseness and vibrations even after long term use and it is connected for rotation to the fan impeller comprising a closed housing wherein are located, symmetrical spaced apart in rapport to the fan axis, at least a pair of radial masses operatively connected via flexible means to an axial hollow operative actuator which is located adjacent to the shutter central vane. When the fan starts to rotate in either direction, each radial mass slides radially outwardly from the axis of rotation of the fan pulling the axial actuator inside the housing allowing the shutter heavy tie rods, by gravity, to open the shutter. When the fan stops, a spring associated with the axial hollow operative actuator pushes it outwardly of the closed housing against the central vane of the shutter causing the closing of the shutter.

Abstract: A fixation pin and methods for attaching an immobilizing device or frame to a bone or to the skull of a patient with a skeletal injury are provided. A preferred embodiment of the pin comprises an externally threaded cylindrical body having on its leading end a shoulder and a smaller diameter coaxial cylindrical post with a rotary cutti ng tip on its face. The post fits snugly into a hole drilled into the bone by the cutting tip without the need for a high axial force to insert and hold the post in place. Drilling t he hole with a rotary cutting tip on the face of the post minimizes lateral damage to the bone. The minimal lateral bone damage and the low axial force provide for a low incidence of pin loosening and side effects such as infections secondary to loosening and headaches.

Title: Adenovirus mutants with deleted protease gene, complementing cell lines and corresponding vectors for gene transfer
Inventor: MASSIE BERNARD
IPC: C12N7/01
Filed: 2000-02-24
Granted: 2010-05-18
Abstract: An adenovirus vector/packaging cell line system is disclosed, in which the vector replication is blocked by deletion of a single gene, which deletion does not interfere with any other viral functions. The deleted gene is the gene of the adenovirus protease. The protease is expressed in a complementing (packaging) cell line through a regulatable expression cassette which induces no toxic effects in the cells, thus making the generation and propagation of the vector easier and more efficient. As the deleted gene is highly specific of adenovirus, no complementation of the gene in transduced cells is expected, which increases the safety of the vectors for gene transfer purposes. Also disclosed is a system of generating recombinant adenovirus vectors by positive selection of recombinants deleted for the endogenous protease, gene which gene is cloned in another region of the adenoviral genome.

Abstract: A method for determining a desirable depth for drilling a horizontal well within an oil reservoir includes the steps of deploying a plurality of data sensors at discrete depths in a subsurface formation penetrated by a wellbore, gathering formation pressure data for the discrete depths using the data sensors, and determining the depth of a reservoir using the gathered formation pressure data. The depth within the reservoir may be determined by identifying from the gathered formation pressure data at least one depth whose corresponding formation pressure is suggestive of a reservoir. Once such a depth is identified, the wellbore itself or a lateral drainhole depending from the wellbore may be steered into the reservoir by maintaining the trajectory of the wellbore or drainhole at a substantially constant distance from a fluid contact within the reservoir.

Abstract: An asymmetric twin waveguide (ATG) structure (11) significantly reduces the negative effects of inter-modal interferences in symmetric twin-waveguide structures and which can be effectively used to implement a variety of optical devices. The ATG structure (11) of the invention can be monolithically fabricated on a single epitaxial structure without the necessity of epitaxial re-growth. The effective index of the passive waveguide in the ATG is varied from that of a symmetric twin waveguide such that one mode of the even and odd modes of propagation is primarily confined to the passive waveguide and the other to the active waveguide (71). The different effective indices of the two coupled waveguides result in the even and odd modes becoming highly asymmetric. The mode with the larger confinement factor in the active waveguide (71) experiences higher gain and becomes dominant. Furthermore, a grating region is incorporated atop the passive waveguide (125) to select certain frequencies for transmission of light through the passive waveguide (125).
